Division 2 General conditions for measurements and calculations:

United Kingdom

Original text. Later amendments are not shown.

  1. (a)

    For the purposes of the calculations set out in points 3 to 8, consumption of electricity shall be multiplied by the conversion coefficient CC of 2,5;

  2. (b)

    Emissions of nitrogen oxides shall be measured as sum of nitrogen monoxide and nitrogen dioxide, and expressed in nitrogen dioxide equivalents;

  3. (c)

    For heat pumps equipped with supplementary heaters, the measurement and calculation of rated heating capacity, seasonal space heating energy efficiency, sound power level and emissions of nitrogen oxides shall take account of the supplementary heater;

  4. (d)

    A heat generator designed for an air heating product, or a housing to be equipped with such a generator shall be tested with an appropriate housing or generator, respectively;

  5. (e)

    A cold generator designed for a cooling product, or a housing to be equipped with such a generator shall be tested with an appropriate housing or generator, respectively.

Notes on Annex III

f1

The wet bulb temperature condition is not required when testing units which do not evaporate condensate.

f2

For units designed for heating and cooling mode, the flow rate obtained during the test at standard rating conditions in cooling mode is used.

f3

Outlet temperatures dependent on water flow rate as determined at standard rating conditions (100 % part load ratio when cooling, 88 % when heating)

f4

With the water flow rate determined during ‘A’ test for units with a fixed water flow rate or with a variable flow rate.

f5

With the water flow rate determined during ‘A’ test for units with a fixed water flow rate or with a variable flow rate.
